On Wednesday, August 19, 2026, UK- and US-based Tiberius Aerospace announced that it is conducting laboratory testing of technologies for the Invictus-200 long-range precision-guided missile. The formal Test & Evaluation phase is intended to validate the concept and technical assumptions behind a next-generation weapon system designed to provide scalable, long-range precision strike capabilities across multiple domains.

Invictus-200 is a tube-launched, multirole weapon system designed for integration with multiple platforms across different operational domains. Its architecture is intended to allow launch from vertical launch systems and autonomous vehicles operating on land and at sea, giving armed forces greater flexibility in how they engage targets at long range.
In May 2025, Tiberius Aerospace introduced its first 155 mm Sceptre (TRBM 155HG) ramjet-assisted artillery munition, which was ordered by the United Kingdom, and the company recently announced successful live-fire testing in the United States. This rapid development and learning process helped accelerate the Invictus program from the laboratory stage into a validated engineering program focused on propulsion, flight performance, guidance, platform integration and manufacturability through formal testing. Related ramjet engine testing for the IVTS-255-LR prototype is already under way at Purdue University’s Zucrow Laboratories, where the prototype has demonstrated excellent functionality using Jet A aviation fuel under all conditions tested to date.
The program addresses an increasingly urgent strategic challenge: the need to rebuild the long-range precision-strike capabilities of the United States and its allies faster than traditional defense production can support. According to emerging reports, the US Army has used up virtually its entire stockpile of MGM-140 ATACMS ballistic missiles and Precision Strike Missiles (PrSM) during the five-month conflict with Iran, intensifying concerns about readiness for future contingencies. Across Europe, Western missile inventories have also come under growing pressure, forcing NATO governments and manufacturers to accelerate production and replenish stockpiles.
For this reason, the Invictus-200 missile is being designed to deliver both combat capability and mass, combining long-range precision-strike performance with an architecture optimized for adaptability and scalable production. The final missile is expected to combine a ramjet engine with an integral rocket booster, enabling speeds of up to Mach 3 and precision strikes at ranges of up to 200 km, with a circular error probable (CEP) of up to 5.5 m depending on the guidance configuration. Its 10–15 kg payload capacity and modular open architecture will allow the system to be configured for different missions and to evolve as operational requirements change.
“The move into formal engineering, testing and evaluation is a major step toward turning Invictus from a promising technology into a deployable capability,” said Chad Steelberg, Founder and CEO of Tiberius Aerospace. “Invictus and Sceptre have been designed from first principles to deliver cost-effective lethality from the outset, using our AI powered platform GRAIL to maximize the combat effect delivered for every dollar spent by simplifying the weapon, engineering it for high-volume production and building in an open architecture that can evolve without replacing the entire system. We have used GRAIL to enable a Silicon Valley approach to product development, connecting program requirements with domestic and allied suppliers capable of producing components and systems and therefore supporting a broader and more resilient industrial base. Invictus will bring together long-range precision, multi-domain flexibility, cost-effective lethality and scalable production in a weapon designed not only for today’s operational requirements, but for continuous adaptation throughout its service life.”
